STAINLESS STEEL DEMISTER PADS: SPECS, SIZES, AND TYPES
Stainless steel demister pads are essential in industries like gas cleaning, chemical processing, oil and gas, HVAC, and refineries. They efficiently remove liquid droplets from gas streams, improving performance and protecting equipment.
- Materials and Construction: These pads are built from corrosion-resistant stainless steel (typically 304 or 316) using woven wire (0.1-1.0 mm wire, 50-500 holes/inch), expanded metal (0.5-5 mm holes), or felted material.
- Size and Dimensions: Thickness varies from 0.5 to 5 mm. Woven wire types have wire diameters of 0.1-1.0 mm and 50-500 holes per inch. Expanded metal pads feature 0.5-5 mm hole sizes. Standard panel sizes range from 300×300 mm to 1000×1000 mm, with custom sizes and shapes available.
- Performance and Efficiency: Demister pads are rated based on their droplet capture ability (usually 1-10 µm). They cause minimal pressure drop (a few to tens of mmWC). Gas flow capacity is measured in m³/h or SCFM.
- Operating Conditions: They can operate in temperatures from below freezing up to 300–400 °C. Stainless steel offers resistance to many chemicals and can handle specific pressure requirements.
- Classification and Standards: These pads meet industry standards like API, ASME, and ISO. They are classified by efficiency: high-efficiency for fine droplets and standard for larger ones. Custom designs are also possible.
- Installation and Maintenance: Demister pads are installed in easily accessible header boxes or separators, often in single or multiple layers. Regular inspection and cleaning are needed, though some models are self-cleaning.
- Customization: Options include materials, coatings, and shapes. The use of stainless steel ensures durability and long-term cost-effectiveness.
